Akemi Hachinohe is a thirty-year-old single woman who leads a quiet, routine life working at a traditional Japanese confectionery shop. Her ordinary days take an unexpected turn after she steps in to help Shion Nikaidou, a fifteen-year-old girl who works part-time at a nearby convenience store. What begins as a simple act of kindness quickly evolves into something far more complicated when the teenager starts making frequent, unannounced visits to Akemi's workplace. As Shion continues to seek out the older woman's company, the dynamic between them shifts from a casual encounter into something much more intense. The situation reaches a critical turning point when the young girl openly confesses her romantic feelings, declaring that she likes Akemi. This sudden and earnest admission leaves the confectionery worker entirely caught off guard, forcing her to confront an emotionally charged dilemma she never anticipated. Now faced with a confession from someone so much younger, Akemi must navigate a delicate and uncomfortable situation. She is left to determine how to appropriately respond to Shion's unwavering affection while managing the boundaries of their age difference and the unexpected disruption to her peaceful daily life.
